History
Founded in September 1998 by five companies
Bluetooth 1.0 specification released in 1999 (Nine promoters)
COMDEX “Best of Show Technology Award” in 1999
2000: First mobile phone, PC Card and headset products, and prototypes of mouse, laptop and USB dongle.
2001: Printer, laptop, hands-free car kit
2002: Keyboard and Mouse, GPS receiver, digital camera
IEEE 802.15.1-2002 based on Bluetooth 1.0b specification
2003: MP3 player, FDA-approved medical system (1M/week)
2004: Stereo headphones, 2.0 + EDR, 250 million devices (3M/week)
2005: Sunglasses (5M/week)
IEEE 802.15.1-2005 based on Bluetooth 1.2 specification
2006: Watch, picture frame, alarm-clock radio (10M/week)
2007: Television, 9,000th member, 2.1 + EDR, here at IEEE 802.11 meeting
Bluetooth Market
Installed base of Bluetooth enabled products reached 1 Billion devices in November of 2006.
Every week, 13 million Bluetooth units are shipped. (~675 million per year or 21 every second)
Every working day, more than five new Bluetooth enabled products are qualified. (~1300 per year)
Broad surveys have shown that the Bluetooth brand is recognized by more than 75% of respondents world-wide. (Millward Brown internet survey for Bluetooth SIG: Bluetooth.org)
Bluetooth Qualification Program
Bluetooth Qualification requires certain testing standards for all designs and products which use the Bluetooth wireless technology.
Qualification is a necessary pre-condition of the intellectual property license for the Bluetooth wireless technology.
Qualification is also a necessary prerequisite in order to apply the Bluetooth trademark to a design or product.
Bluetooth Profile Tuning Suite has been developed as a reference test system to ensure Bluetooth interoperability.
The Bluetooth Wireless Experience:
Replaces cables connecting portable and/or fixed devices while maintaining high levels of security,
Robust, low power, low cost solution,
Any Bluetooth enabled device, almost everywhere in the world, can connect to other Bluetooth enabled devices in proximity,
Bluetooth enabled devices with common profiles work together to provide a uniform user experience

Consumer Electronics
Billions of Bluetooth-enabled Devices
Motorola expects that over 75% of our mobile phone production will include Bluetooth by 2007.
Bluetooth Mobile Handset Use Cases
Headset and Hands Free Operation in Vehicles
Synchronization of Personal Information
Remote Access Link for PCs
Moving Digital Images, Video Clips, and Music
Streaming Music to Other Devices
Printing of Digital Images
Remote Control of Other Devices
Integration with DLNA/UPnP
Future of Bluetooth Wireless Technology
Expect to ship 2 Billion devices in 2011
Ultra Low Power devices
Suitability for high speed applications for digital imaging, music, and video transfer
Improved interoperability
Bluetooth Wireless Experience
Bluetooth Alternate MAC/PHY Approach
Bluetooth page link used to discover peer device, authenticate, discover capabilities (e.g., 802.11), and initiate operation
802.11 page link enabled and used when higher performance required
802.11 page link idled when operation completed
GENERIC ALT MAC/PHY ARCHITECTURE
The AMP architecture modifies the standard Bluetooth architecture by enabling multiple alternate radios under L2CAP
Discovery, connection set up and low power connections still use the 2.4GHz radio
The new AMPs are used as high speed channels
802.11 Alternate MAC/PHY (AMP)
Bluetooth/802.11 combo chips on the market
Both technologies in the mobile device
Bluetooth in ~50% of mobile phones (500M in 2007)
802.11 only in 20M mobile phones in 2007
Leverage 802.11 in AMP
Enable high-speed use cases
Create market that will increase Bluetooth+802.11 in mobile devices to more than 50% of TAM by 2010 (~600M devices)
Bluetooth market 1B/year by 2009
Current 802.11 market projection only 500M/year by 2009
Linkage with Bluetooth could double 802.11 market by 2010
Synchronization with 802.11 AP
Example Synchronization Use Case
Mobile phone discovers PC using Bluetooth technology and sets up an 802.11 MAC/PHY connection for a high speed synchronization application
Synchronization with 802.11 AP
Example Synchronization Use Case
Mobile phone discovers PC using Bluetooth technology and sets up an 802.11 MAC/PHY connection for a high speed synchronization application
Synchronization without 802.11 AP
Example Synchronization Use Case
Mobile phone discovers PC using Bluetooth technology and sets up an 802.11 MAC/PHY connection for a high speed synchronization application
POTENTIAL COLLABORATION AREAS
Liaisons have been identified (IEEE 802.11 and WFA)
Evaluate common use cases and market requirements
Ensure reasonable levels of coexistence
Identify areas where improvements to 802.11 standards are desired
